Every year, celebrities gather to rejoice in film, art, and, style during awards season — and the Golden Globes of 2018 were no disappointment. The famous folks all gathered on the red carpet, most of whom dressed in black in solidarity for the Time’s Up movement. Much like #MeToo, Time’s Up stands with women against sexual harassment — and the number of men and women standing together was staggering.

Justin Timberlake was just one of the celebs for the Time’s Up movement, and he showed his support via Twitter. His fans weren’t so receptive to his tweet, however — and he’s not the only one who received some backlash. Here’s what happened.

Many celebrities wore Time’s Up pins on the red carpet

If you looked closely at what the stars were wearing to the Golden Globes, you’ll see most of them sporting Time’s Up pins. These black-and-white pins were worn on everyone from Timberlake himself to Ewan McGregor, Michelle Pfeiffer, the Jonas Brothers, and Ryan Seacrest, The New York Times reports.There were 500 designs of the pin produced in two weeks before the final one was made. While the movement has no defined leader, notable women like Natalie Portman and Reese Witherspoon have spoken in support of it, too.

And this celebrity was under fire following the night’s events

James Franco won an award and sported a Time’s Up pin at the event, but many weren’t pleased to see his support. The New York Daily News reports actress Violet Paley says Franco sexually assaulted her once, and that he offered his hotel room up to her 17-year-old friend. Others remember inappropriate behavior from Franco at his acting school, too.

Elisabeth Moss’ acceptance speech felt hypocritical to some, too

Her roll in The Handmaid’s Tale already garnered backlash once fans knew she was a Scientologist. And when Elisabeth Moss mentioned women’s equality in her Golden Globes acceptance speech, many thought it was incredibly hypocritical.

Daily Mail Online explains there are allegations against the Church of Scientology stating it covers up sexual assaults. Many believe the church knew about the rape claims against fellow Scientologist Danny Masterson before they hit public news. As one Twitter user notes, her solidarity with the Time’s Up movement doesn’t seem authentic considering she’s part of “an organization which silences women more than any other.”

And not all celebrities felt the need to wear black in solidarity

While every celebrity attending the event received the all-black memo, a few chose not to partake. Blanca Blanco was one such celeb who showed up in a bright red dress. Many accused her of being against the movement, since she knew the dress code. But she disagrees.

“Wearing red does not mean I am against the movement,” Blanco told Fox News. “I am excited about the #TimesUp movement; true change is long overdue.”

As for others who shamed her for wearing a skimpy dress to the event, she said shaming is also part of the problem.

Justin Timberlake’s tweet that caused the firestorm

It wasn’t just James Franco and Elisabeth Moss who raised eyebrows for their support. Justin Timberlake posted a photo of him and his wife, Jessica Biel, on Twitter before the awards show. They both wore black, and he adorned a Time’s Up pin.

Here’s the problem, though: Timberlake is involved in the new Woody Allen movie, WonderWheel, Elle reports.And no one can forget the multiple sexual abuse claims against Allen. “You gotta quit working with Woody Allen if you’re gonna wear that pin, love,” said one Twitter user in response.

He’s not the only one who received Twitter backlash

It seemed ironic to Twitter that Ivanka Trump would comment on the Time’s Up movement considering her father has been accused of sexual assault by 13 women. Ivanka posted, “Just saw @Oprah’s empowering & inspiring speech at last night’s #GoldenGlobes. Let’s all come together, women & men, & say #TIMESUP!”

Some stars, like Chrissy Teigen and Alyssa Milano, responded unhappily, Yahoo reports. Another Twitter user said, “Honestly Ivanka, it took a staggering level of heinous idiocy for you to post this tweet.”

It’s clear (almost) everyone in Hollywood is willing to wear black and show their support for the movement — but Time’s Up has also received some backlash. The Daily Beast reports Rose McGowan, who was one of the first women to accuse Harvey Weinstein of rape, is unimpressed by the movement.

McGowan called Hollywood talent agency CAA “a company of pimps that sent so many into the monster’s lair.” Yet, many Time’s Up gatherings occurred in CAA offices. Also, Fox news contributor Tamara Holder tweeted that the same Hollywood agencies donating to Time’s Up were “complicit in the destruction of women’s careers.” Interestingly enough, McGowan didn’t get an invite to the Globes despite her heavy contribution to the #MeToo movement.
